ABSTRACT

Food allergy is a state of immunologic reaction resulting from the exposure to food or food additive. The clinical symptoms and signs varied from localized symptoms at the site of direct contact such as contact urticaria, localized gastrointestinal symptoms with nausea, pain, vomiting and diarrhea to systemic symptoms occurring in remote organs, such as skin, respiratory system, cardiovascular system. We reported a case of 8 month-old girl with milk allergy who presented skin symptoms after cutaneous contact with milk protein. Developed after 15 minutes of milk contact challenge on forearm and followed by erythematous papules and wheals distributed throughout the face and neck area accompanied by edema and itching. The symptoms were continued for 2 hours and disappeared after an injection of pheniramine maleate.
